Impact of rainbow trout on aquatic invertebrate communities in subtropical mountain streams of northwest Argentina
Provedor de dados: 67
Autores: Molineri,Carlos.
The present study was conducted to assess the effect of rainbow trout introduction on benthic invertebrate communities, stratified as epibenthos and infauna. Two main questions are explored: 1) do the trout-invaded streams show a different community structure than the streams with autochthonous fish?, and 2) does the presence of trout affect differentially the epibenthos and the infauna? Epibenthic and infaunal samples, drift samples and fish stomach content were sampled four times from three stations to assess the impact of rainbow trout (Oncorhynchus mykiss) on the invertebrate aquatic fauna. Only one species of native fish was recorded in the studied sites, the siluriform Trichomycterus corduvense. Both fish species were found always in allopatry. The...

Spatial-temporal patterns of functional feeding groups in mountain streams of Córdoba, Argentina
Provedor de dados: 67
Autores: Príncipe,Romina E; Gualdoni,Cristina M; Oberto,Ana M; Raffaini,Graciela B; Corigliano,María C.
Trophic structure of benthic communities is influenced by the availability of food resources which indeed may be conditioned by stream size, shading and substrate. This study aims to analyze the distribution of macroinvertebrate Functional Feeding Groups in different habitats of mountain streams (Córdoba, Argentina) and to assess the environmental variables conditioning this distribution at the habitat level. Four streams were sampled in two hydrological periods (high and low discharge) and three benthic samples were taken in riffles and runs of coarse and fine substrate. Gathering collectors were dominant in most of the habitats, streams and periods except in riffles during the low water period in which filtering collectors dominated. At the habitat...

Oxygen deficiency and benthic communities in the peruvian upper continental margin
Provedor de dados: 72
Autores: Gutiérrez,Dimitri; Quipúzcoa,Luis; Enríquez,Edgardo.
The oxygen minimum zone (OMZ) off the Peruvian coast, though shallower and more intense than other OMZs, exhibits a spatial distribution that varies with latitude, depth and distance to the coast. The spatial variability in oxygen content imposes latitudinal and bathymetric zonations of the benthic communities. Nevertheless the spatial patterns of the benthic communities are also modulated by the bottom topography and the sedimentary environments, which in turn are controlled to a large extent by the poleward undercurrent. While the bathymetric patterns of the macro- and meiobenthos have been previously described, latitudinal changes have received less attention. We found that, in parallel with opposed latitudinal gradients of oxygen and fresh organic...

Autores: Заика, В. Е.; Сергеева, Н. Г.
Изложены материалы по вертикальному распределению донных Ciliophora в Чёрном море на глубинах от 120 до 2075 м. Сероводород начал регистрироваться со 160 – 170 м. Отмечено три пика обилия цилиат на глубинах 120, 160 и 240 м.  Средний пик обилия приходится на глубины появления сероводорода. Кроме того, по имеющимся данным, на тех же глубинах находятся пелагические пики интенсивности бактериального хемосинтеза и продукции бактерий. Следовательно, пики обилия инфузорий можно связать со скоплениями пищи. В других меромиктических водоёмах сгущения микропланктона тоже наблюдаются в области перехода от аэробных вод к анаэробным. Наибольшее число морфотипов цилиат (8) было на глубине 240 м, в области нижнего пика обилия.

Temporal and spatial variation of rocky shores intertidal benthic communities in Southeast Brazil
Provedor de dados: 76
Autores: Zamprogno,Gabriela C.; Fernandes,Flavio C.; Fernandes,Luiz L.
The relationships between environmental factors and temporal and spatial variations of benthic communities of three rocky shores of the state of Espírito Santo, Southeast Brazil, were studied. Sampling was conducted every three months, from August 2006 to May 2007, using intersection points. Chthamalus bisinuatus (Pilsbry, 1916) (Crustacea) and Brachidontes spp. (Mollusca) were the most abundant taxa, occupying the upper level of the intertidal zone of the rocky shore. The species richness was higher at the lower levels. The invasive species Isognomon bicolor (C. B. Adams, 1845) (Mollusca) occurred at low densities in the studied areas. The clustering analysis dendrogram indicated a separation of communities based on exposed and sheltered areas. According...

Biometry of neotropical invertebrates inhabiting floodplain rivers: unraveling bionomy
Provedor de dados: 76
Autores: Zilli,Florencia; Barco,Julia del; Vanzetti,Agustín.
ABSTRACT Currently, it is widely recognized that invertebrates play key roles in neotropical floodplains and in many other environments worldwide. However, little information has been published concerning their biometry, in spite that it represents an essential tool for many different studies. Here, we provided length-mass and length-length relationships by fitting the linearized model (log10 Y = log10a + b log10 X) and several mean biomass ratios ± SE for bivalves, gastropods, quironomids, ephemeropterans, oligochaetes and hirudineans. We measured, weighed, oven dried and incinerated to ashes specimens collected from 2005 to 2014 in the Paraná River, Argentina. The lineal equations had fit levels higher than 75% in most of the significant regressions....

Seasonal variability on the structure of sublittoral macrozoobenthic association in the Patos Lagoon estuary, southern Brazil
Provedor de dados: 76
Autores: Colling,Leonir A.; Bemvenuti,Carlos E.; Gandra,Michel S.
The aim of this study is to analyze and relate the spatial-temporal variability of macrozoobenthic assemblages to bottom characteristics and salinity fluctuations, in an estuarine shallow water region of Patos Lagoon. Monthly samples, between September 2002 and August 2003, were taken on six sampling stations (distant 90 m). Three biological samples with a 10 cm diameter corer, one sample for sediment analysis, fortnightly bottom topography measurements, and daily data of temperature and salinity were taken from each station. Two biotic and environmental conditions were identified: the first corresponding to spring and summer months, with low macrozoobenthos densities, low values of salinity, small variations in bottom topographic level and weak...

Ecosystemes benthiques profonds et chimiosynthese bacterienne: Sources hydrothermales et suintements
Provedor de dados: 5
Autores: Laubier, Lucien.
Hydrothermal communities of various species compositions have been described from the eastern and western Pacific and Atlantic. Brine and cold seeps and hydrocarbon seepages have been found off Florida, off the Oregon and Japanese subduction systems, on the Laurentian Fan, near Barbados, and off Louisiana. Biomasses range from 10 to 70 kg/m super(2), fresh weight. Basic microdistribution of species groups in aureoles centered around hydrothermal vents reveals different levels of adaptation to harsh physico-chemical conditions. Two groups of primary producers can be recognized: a highly efficient cool water group with large vestimentiferan tube worms and bivalves, and alvinellid polychaetes adapted to hot waters. Both groups are exploited by specific...

Biological availability of sediment-bound trace metals.
Provedor de dados: 5
Autores: Luoma, S.
It has been established that direct uptake of (at least some) trace metals from sediments contributes to metal concentrations in benthic organisms. Important controls on metal uptake from sediment are the concentration of the exposure, the partitioning of the metals among components of the sediment, and the redox potential of the sediment. Important problems in ecology, physiology, geochemistry and biogeochemistry remain unresolved, however, and a concentrated interdisciplinary research effort will be necessary before a complete understanding of the fate and impact of sediment-bound metals will be possible.

Autores: Cabioch, L; Retiere, C.
The waters of the Seine River are polluted by urban, industrial and agricultural effluents. In addition direct industrial wastes inputs are emptied into the estuary. Within the limits of the Seine Bay program it was not possible to research pollution impacts on every estuarine ecosystem link; so only benthos have been studied. To take time response of organisms into account, the authors have defined indicators or quantitative evaluation of parameters, reflecting physiological state. They have studied population fluctuations caused by natural or man induced effects.

The eastern English Channel, the narrow channel of water separating northern France and southeast England is an area of intense human use of the array of resources concentrated into its relative small area. The vulnerability of living resources and their habitats brought together French and British maritime experts within a common project (called CHARM): to create an atlas of marine resource habitats in the eastern English Channel so as to provide planners and decision-makers with the necessary information to help managing the use of its living and non-living resources. This multidisciplinary and richly illustrated atlas provides abundant information on the legal framework and physical environment; benthic invertebrates, fish and their habitats; fishing...

This is the 38th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, and zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by...

Pre- and post-settlement events in benthic community dynamics
Provedor de dados: 5
Autores: Fraschetti, S; Giangrande, A; Terlizzi, A; Boero, F.
In all marine benthic environments, organism replacement depends on recruitment limitation, i.e. the impact of both pre- and post-settlement events on the success of recruitment. The relative contribution of pre- versus post-settlement processes in shaping adult populations has been extensively studied. Most analyses concluded that recruitment limitation is a strong determinant of adults' density. The magnitude of its limitation depends on context, varies with species, and can be strongly modified by all the events preceding and following recruitment itself. A comparison of the outcome of recruitment limitation on hard- and soft-bottom communities has often been neglected. The rules governing these two environments, in both the inter- and the subtidal,...

Autores: Trenkel, Verena; Le Loch, Francois; Rochet, Marie-joelle.
In the summer of 2004, a video survey was carried out in the northern part of the central mud bank (Grande Vasiere) of the Bay of Biscay to study the small scale relationship between the dominant crustacean megafauna Nephrops norvegicus, Munida rugosa and Goneplax rhomboides and juvenile hake (Merluccius merluccius). Using a towed body, high-resolution videos were recorded in six sampling sites. Statistical modelling using generalised additive models (GAM) revealed variations in activity patterns for two species. More N. norvegicus were observed outside their burrows at dawn and somewhat at dusk (no observations during night) while G. rhomboides was less observed in the morning. In addition, reduced spatial overlap between G. rhomboides and N. norvegicus...

This is the 36th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, and zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by...

Long-term variability of the Abra alba community in the southern bight of the North Sea
Provedor de dados: 5
Autores: Carpenter, P; Dewarumez, Jm; Lepretre, A.
The Abra alba community from the Gravelines area has been studied since 1976. During this period, sudden and unpredictable variations of the species composition have been observed. These important changes affect a limited number of species without changing the bionomical structure of the community. The species in question are found to be characteristic of this community, and are the more abundant ones. Multivariate statistical methods were used to study quantitative data on the benthic population collected from 1978 to 1992. This analysis was performed in association with air temperature data. Results showed the existence of a six- or seven-year cycle, and this is confirmed by the observation of two complete periods. This cycle, which is found to be...

This report is the 18 th on annual surveillance of the nuclear plant site of Gravelines. In 1996, mean power output was 4160 MW with a cooling flow rate of 213 m3 / sec leading to an outfull vT of 9°26. The major impact of chloration is due to bromoform (18.3 ug / 1) in outflow. The amplitude of the vibrio annual cycle is stable when compared to previous years but diversity increases. In 1996, earlyness in species reproduction was noticeable. Chlorophyll biomass reached 45 mg / m3 and noctiluca cycle was quite unusual. Impact is estimated aroud 20 - 40 % in phytoplankton biomass and 30 - 100 % in zooplankton, depending on the species. Subtidal abra alba populations have been studied. For intertidal populations disappearance of spio martinensis is to be...

Autores: Dauer, Dm.
Long-term trends in subtidal macrobenthic communities of the lower Chesapeake Bay, USA, were examined using data collected quarterly (March, June, September and December) fr om 1985 through 1993 at 16 stations along a salinity gradient from tidal freshwater regions of the major tributaries (James, York and Rappahannock rivers) to the polyhaline region of the mainstem of Chesapeake Bay. In March 1989 two stations were added to the program in the mesohaline region of the Southern Branch of the Elizabeth River, a region characterized by contaminated sediments. A non-parametric trend analysis procedure was applied to five parameters characterizing macrobenthic community structure: community biomass, species richness, abundance of individuals, proportion of...

Epifaunal community structure associated with Riftia pachyptila aggregations in chemically different hydrothermal vent habitats
Provedor de dados: 5
Autores: Govenar, B; Le Bris, Nadine; Gollner, S; Glanville, J; Aperghis, A; Hourdez, S; Fisher, C.
The vestimentiferan tubeworm Riftia pachyptila (Polychaeta: Sibloglinidae) often dominates early succession stages and high productivity habitats at low-temperature hydrothermal vents on the East Pacific Rise. We collected 8 aggregations of R. pachyptila and the associated epifaunal community at 2 discrete sites of diffuse hydrothermal activity, in December 2001 and December 2002. Because of the high spatial and temporal variability of the biotic and abiotic factors related to hydrothermal vent activity, significant differences in the structure and the composition of the community were expected to occur at the scale of either 1 yr or 500 m distance between very different sites. There was no significant difference in the temperature ranges of the diffuse...

Fish faunal and habitat analyses using trawls, camera sleds and submersibles in benthic deep-sea habitats off central California
Provedor de dados: 5
Autores: Cailliet, Gm; Andrews, Ah; Wakefield, Ww; Moreno, G; Rhodes, Kl.
Beam trawl, camera sled and submersible data from 2 000-3 300 m off central California produced similar fish faunal composition, but different density estimates. All species caught in trawls were observed in camera-sled and submersible observations. However, some rare species that were observed were not caught in trawls. The fish fauna was dominated by the families Macrouridae, Zoarcidae, Moridae, and Rajidae. Fishes both trawled and observed were the macrourids Coryphaenoides armatus, C. filifer and C. leptolepis; the zoarcids Bothrocara spp., Pachycara lepinium and Lycenchelys spp.; the morid Antimora microlepis; the rajid Bathyraja trachura, the ophidiid Spectrunculus grandis, and the liparidid Careproctus ovigerum.

With increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyze species’ potential resistance to future mining and perform meta-analyses on population density and diversity recovery after disturbances most similar to mining: volcanic eruptions at vents, fisheries on seamounts, and experiments that mimic nodule mining on abyssal plains. We report wide variation in recovery rates among taxa, size, and mobility of fauna. While...

Development of a biologically based environmental quality standard from a long-term benthic monitoring programme in the North Sea
Provedor de dados: 5
Autores: Brown, Ar; Shillabeer, N.
The paper describes the derivation and effectiveness of a benthic macrofauna environmental quality standard (EQS). The EQS is derived from a continuing, long-term (24 years) monitoring programme, designed to determine the effect of mining effluent discharged into coastal waters off the NE coast of England. The area under study is at the Cleveland Potash mine at Boulby. Benthic monitoring began there in 1970 and live years of baseline data were gathered before discharge commenced in 1974. During the course of the monitoring programme (1970-1993) annual surveys have been completed at the discharge point and at more distant reference sites. The complete data set includes results from over 1000 benthic grab samples. The effect of the discharge is clearly...

Within the COST action EMBOS (European Marine Biodiversity Observatory System) the degree and variation of the diversity and densities of soft-bottom communities from the lower intertidal or the shallow subtidal was measured at 28 marine sites along the European coastline (Baltic, Atlantic, Mediterranean) using jointly agreed and harmonized protocols, tools and indicators. The hypothesis tested was that the diversity for all taxonomic groups would decrease with increasing latitude. The EMBOS system delivered accurate and comparable data on the diversity and densities of the soft sediment macrozoobenthic community over a large-scale gradient along the European coastline. In contrast to general biogeographic theory, species diversity showed no linear...

This is the 39th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached a maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, and zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by...

Relations milieu-ressources : impact de la conchyliculture sur un environnement lagunaire méditerranéen (Thau)
Provedor de dados: 5
Autores: Deslous-paoli, Jean-marc; Souchu, Philippe; Mazouni, N; Juge, Claude; Dagault, Francoise.
Shellfish farming leaves its mark on the environment in which it has developed, and the men who depend upon it. These changes have altogether balanced the lagoon cycle and have caused disastrous episodic events. Increased water c1arity caused by the uptake of particulate material by shellfish farming allows seagrass to grow in deeper areas of the lagoon (down to five metres). Shellfish farming nutrient transformations increase ecosystem productivity, even if the filtration pressure keeps phytoplankton biomass at a low leveI. Storage of phosphorus and nitrogen in animal tissue limits eutrophication in this ecosystem. Transfer of oysters from growout facilities increases animal and vegetal specific diversity. The presence of large amounts of shellfish allows...

Deep-sea demersal fish density estimates compared from simultaneous net catches and photography
Provedor de dados: 5
Autores: Russell, Ra; Serafy, J.
The numbers of fish caught and photographed in the eastern North Atlantic (49-52°N and 10-15°W) were compared from 46 hauts, made between 1979 and 1983 using an epibenthic sledge with an ancillary camera. There were 1966 specimens captured and 258 photographed. Fish species of similar appearance were grouped to aid identification from photographs. The 20 speciesjgroups common to both gears were represented by 83.6% of the specimens captured. Although there was good correlation between the numbers, catch density was about one third of that photographed, demonstrating how much such estimates may be at variance. Larger species showed a greater discrepancy, to suggest net avoidance. A bow-wave might sweep aside less active animais. The camera also demonstrated...

Élaboration d'un diagnostic robuste de mise en place d'aires marines protégées, dans un contexte d'incertitudes
Provedor de dados: 5
Autores: Gasche, Loic.
The Eastern Channel is a strategic area that supports many human activities, in particular fishing, freight, aggregates extraction and tourism. Many zones have also been identified that are suitable to host windfarms. A good understanding of interactions between these activities is necessary in order to estimate, forestall and manage risks of major spatial conflicts. Besides, their potential interactions with marine populations have not yet been well established. Several Marine Protected Areas (MPAs) have been created in the Channel in the past few years, to protect key habitats or populations, or are still being discussed. It is necessary to predict to what extent these MPAs can be an asset for a sustainable exploitation of marine resources, and what...

INTRODUCTION:  The Dover Strait (Figure 1) connects the North Sea to the English Channel. Here, northern France and South-East England are at their closest. This narrow corridor, one of the world's busiest straits for maritime shipping, is a key economic area for numerous activities, such as leisure and tourism, international ports and shipping, plus the exploitation of living or abiotic marine resources. This area is a significant resource for fisheries because many commercial fish species are abundant there, but also because of the presence of nursery and spawning areas and migratory routes linked to specific environmental characteristics. The vulnerability of these resources, which are subjected to strong anthropogenic pressures, has brought together...

Long-term changes (1979-1994) in two coastal benthic communities (English Channel): analysis of structural developments
Provedor de dados: 5
Autores: Davoult, D; Dewarumez, Jm; Migne, A.
The long-term variations of two coastal benthic communities (Eastern English Channel, France) were studied between 1979 and 1994 by means of factor correspondence analysis (FCA), trophic structure and rank-frequency diagrams (RFD). FCA identified periods of relative homogeneity and periods of strong variation in the structure of the two communities. The first community, established on heterogeneous sand, showed a multi-annual cycle Linked to grain-size variations in the sediment. As passive supplies of organic matter were not important and suspension feeders could hardly live in these conditions, the community remained poor and stable and was dominated by deposit-feeders and carnivores. The other one, a rich and diverse mussel (Mytilus edulis) bed, showed...

Measurements were performed in spring and summer on a tidal sandflat of the Rance estuary (south part of the Western English Channel) colonized by the Manila clam after its deliberate introduction in the 1990's. Benthic inorganic carbon fluxes were measured using light and dark benthic chambers both at emersion and immersion. Benthic nutrient fluxes were measured using dark benthic chambers at immersion. Inorganic carbon (IC) and ammonium sediment release under darkness at immersion reached 5.60 mmol m−2 h−1 and 441 μmol m−2 h−1 respectively for a clam density of...

How do macrobenthic resources concentrate foraging waders in large megatidal sandflats?
Provedor de dados: 5
Autores: Ponsero, Alain; Sturbois, Anthony; Desroy, Nicolas; Le Mao, Patrick; Jones, Auriane; Fournier, Jerome.
The relationship between foraging shorebirds, macrobenthos and sedimentary parameters has been widely studied across Western Europe. Megatidal areas have large zones uncovered when the water retreats. Consequently, in such cases, the tide also influences foraging activities. This paper examines the use of an intertidal space by waders to define how macrobenthic resource concentrates foraging activity of birds in a large megatidal sandflat. This approach combines accurate spatial distribution of waders (Oystercatcher, Eurasian curlew, Bar-tailed Godwit and Redknot) according to their activity with ecological/biological parameters. A differential exploitation of the flat is clearly shown, with macrobenthic biomass appearing as one of the main explanatory...

Changes over a period of thirty years in a circalittoral mud community (% silt greater than or equal to 75) in the Gulf of Fos (French, Mediterranean coast) have been followed at three sites spaced along a transect NNW-SSE at depths of 15, 35 and 70 m. The results clearly show how the macrobenthic community at the three sites has been influenced by the construction of the port of Fos, notably as a consequence of sediment suspension during the dredging of the docks and the access channel, but also due to the dumping at sea of dredged material (more than 100 x 10(6) m(3) were dredged, about a quarter of which was dumped at sea, at depths of 30 to 60 m). The grouping of the samples taken before, during and after the development of the port (1963-1964, from...

R.; O'Neill, F. G.; Piet, G. J.; Polet, H.; Sala, A.; Smith, C.; Van Denderen, P. D.; Van Kooten, T.; Zengin, M.
A framework to assess the impact of mobile fishing gear on the seabed and benthic ecosystem is presented. The framework that can be used at regional and local scales provides indicators for both trawling pressure and ecological impact. It builds on high-resolution maps of trawling intensity and considers the physical effects of trawl gears on the seabed, on marine taxa, and on the functioning of the benthic ecosystem. Within the framework, a reductionist approach is applied that breaks down a fishing gear into its components, and a number of biological traits are chosen to determine either the vulnerability of the benthos to the impact of that gear component, or to provide a proxy for their ecological role. The approach considers gear elements, such as...

The optimization of Ifremer's survey as a support of MSFD monitoring has been available since 2016 on the offshore fisheries surveys. Several protocols have been implemented, such as the “seafloor litter” and “gelatinous zooplankton” protocols. The aim of both protocols is to respectively collect data about the spatio-temporal evolution of waste and determine their origin, and to monitor the biodiversity of gelatinous zooplankton. From September to November 2017, they were tested on coastal surveys: NOURSOM, NOURNEINE, NOURMONT, ORHAGO, and NURSE. These surveys were primarily deployed to estimate the bentho-demersal species stocks as well as their spatio-temporal and trophic dynamics by a standardized sampling. Thus, this paper aims to assess the...

Influence of hydro-sedimentary factors on mollusc death assemblages in a temperate mixed tide-and-wave dominated coastal environment: Implications for the fossil record
Provedor de dados: 5
Autores: Poirier, Clement; Sauriau, Pierre-guy; Chaumillon, Eric; Bertin, Xavier.
Mollusc death assemblages were recovered in 98 subtidal sampling stations on the seafloor of the shallow Pertuis Charentais Sea (Atlantic coast of France). Taxonomic composition and spatial distribution of death assemblages were investigated, as well as their response to sediment grain size (field data), bottom shear stress (coupled tide and wave hydrodynamic modelling), and sediment budget (bathymetric difference map) Results showed that molluscs are likely to be reliable paleoenvironmental indicators since death assemblages were able to acquire ecological changes within years (decadal-scale taphonomic inertia), and live-dead agreement inferred from existing data on living benthic communities was high, except close to river mouths and intertidal mudflats...

The occurrence of hydrothermal vent ecosystems at Secca delle Fumose, Pozzuoli Bay (Gulf of Naples), represented an opportunity to study the benthic assemblages under the thermal stress of hydrothermal emissions in a very shallow environment (9–14 m water depth). In autumn 2016, the macrobenthic community was sampled by scuba divers at four sites located in the Baia Underwater Archeological Park. Two sites were characterized by vent emissions (one with white bacterial mat scattered on the bottom and one with a yellow substrate around a geyser opening) and two at about 100 m away, used as control. Sediment and interstitial water environmental variables were measured to determine their influence on the structure of macrobenthic assemblages. A total of 1,954...

Spatial and temporal interaction between sediment and microphytobenthos in a temperate estuarine macro-intertidal bay
Provedor de dados: 5
Autores: Orvain, Francis; Lefebvre, Sebastien; Montepini, J.; Sebire, M.; Gangnery, Aline; Sylvand, B.
Intertidal flats of the estuarine macro-intertidal Baie des Veys (France) were investigated to identify spatial features of sediment and microphytobenthos (MPB) in April 2003. Gradients occurred within the domain, and patches were identified close to vegetated areas or within the oyster-farming areas where calm physical conditions and biodeposition altered the sediment and MPB landscapes. Spatial patterns of chl a content were explained primarily by the influence of sediment features, while bed elevation and compaction brought only minor insights into MPB distribution regulation. The smaller size of MPB patches compared to silt patches revealed the interplay between physical structure defining the sediment landscape, the biotic patches that they contain,...

This is the 24th annual surveillance report concerning the central nuclear power plant of Gravelines. This very high power level (5400 MW) results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveillance studies concern monitoring of fish populations (larvae and eggs of Sole and Sprat) or crustaceans( shrimps), benthic system (intertidal and subtidal) and pelagic system (hydrology, microbiology, phytoplankton, zooplankton). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term...

Relationship between sedimentary organic matter and benthic fauna within the Gulf of Lion: synthesis on the identification of new biochemical descriptors of sedimentary organic nutritional value
Provedor de dados: 5
Autores: Gremare, A; Medernach, L; Debovee, F; Amouroux, Jm; Charles, F; Dinet, A; Vetion, G; Albert, P; Colomines, Jc.
The abilities of several biochemical characteristics of sedimentary organic matter to describe quantitative changes in benthic fauna were assessed based on several surveys carried out within the Gulf of Lion during the last decade. Two sets of high frequency samplings were carried out both inshore and offshore, together with an assessment of seasonal variability along a depth gradient, and a synoptic assessment of mesoscale spatial variability. The considered biochemical parameters were: total organic matter, organic carbon, nitrogen, total proteins, available proteins, carbohydrates, lipids, total and available amino acids. The considered faunal parameters were the abundance and the biomass of both meio- and macrofauna. Our results contribute to unravel...

Exploitation of intertidal feeding resources by the Red Knot Calidris canutus under megatidal conditions (Bay of Saint-Brieuc, France)
Provedor de dados: 5
Autores: Sturbois, Anthony; Ponsero, Alain; Desroy, Nicolas; Le Mao, Patrick; Fournier, Jerome.
The feeding ecology of the red knot has been widely studied across its wintering range. Red knots mainly select bivalves and gastropods, with differences between sites due to variation in prey availability. Shorebird’s diet is also influenced or controlled by the tidal regime. The aim of this paper is to demonstrate the adaptation of foraging red knots to the megatidal environment. The variation in their diet during tidal cycles was studied in the bay of Saint-Brieuc, a functional unit for this species. The method used combined macrofauna, distribution of foraging birds and diet data. Comparative spatial analyses of macrofauna and distribution of foraging red knots have shown that the bay's four benthic assemblages are exploited by birds. By analysing...

Changes in the intertidal community structure after a mass mortality event in sandy beaches of Argentina
Provedor de dados: 16
Autores: Dadon, J.R.
After a massive mortality of the dominant species (the clam Mesodesma mactroides) occurred in 1995, changes in the intertidal community in sandy beaches of Argentina were monitored. Eight sampling stations were established in a 40 km open stretch and samples were taken every October each year up to 2001. Biomass, density, size frequency distribution and mean growth rates for the most abundant species were analyzed. During the mortality event, only the benthic stages of M. mactroides were affected, their total mean biomass diminishing from 1,399 g to 2 g per running meter beach. Post-mortality recruitment was normal and the growth rates for the youngest cohorts were similar to those previously reported. After a two years’ lag, the wedge clam Donax...

Re-description of Phymactis papillosa (Lesson, 1830) and Phymanthea pluvia (Drayton in Dana, 1846) (Cnidaria: Anthozoa), two common actiniid sea anemones from the south east Pacific with a discussion of related genera
Provedor de dados: 16
Autores: Häussermann, V.
Actiniid sea anemones possess few characteristics of taxonomic value, which makes columnar outgrowths one of the most important features for systematic work. There are two species of actiniid sea anemones known from Chile and southern Peru that exhibit a column densely covered with non-adhesive vesicles: Phymactis papillosa (Lesson, 1830) (= Phymactis clematis) and Phymanthea pluvia (Drayton in Dana, 1846). Hereby both are re-described in detail. The re-descriptions are based on observations of about 100 living animals in their habitat and in aquaria and on the examination of 21 specimens of P. papillosa and seven specimens of P. pluvia collected in Chile between 1995 and 2003. In Chile, specimens of both species occur in tide-pools, on vertical and...

Autores: Schejter, L.; Bremec, C.
Flexopecten felipponei (Dall, 1922) is a non-commercial, seldom reported pectinid from the SW Atlantic Ocean. In this contribution we review its taxonomy, describe epifaunal species and their levels of encrustation, and discuss the composition of the macrobenthic assemblage where this scallop Iives. Eighteen epibiont taxa were observed to Iive on the valves of these scallops. The most frequent and abundant epibionts on F. felipponei were serpulids, barnacles, and oysters. Although both valves were encrusted, the left valves had higher percentages of coverage. The benthic community contained 69 invertebrate taxa that generally charaeterize other mid-shelf bottorns between 37°S and 39°S. Eight pea crabs of the species Tumidotheres maculatus (Say, 1818)were...

Autores: Gaitán, E.N.
Two of the most important frontal systems of the Argentine Sea (SW Atlantic Ocean) were compared to obtain evidences on the regulatory mechanisms of food web length, incorporating both spatial (areas within fronts) and temporal (presence or absence of frontal structure) variability. The stable isotopes of Carbon and Nitrogen were used to evaluate the origin and composition of the organic matter used by primary consumers, the structure of food webs, the trophic levels of several taxa and the benthic-pelagic coupling within each system. In the Río de la Plata estuarine front, different sources of organic matter would support the food webs occurring in the three areas of the system. The particulate organic material (POM) would be the main resource supporting...

Autores: Arencibia, G.; Capetillo, N.; Castro, M.; Ortega, A.
Las redes de estaciones de monitoreo o muestreos empleadas en estudios ambientales dentro de amplios ecosistemas marinos, como extensas bahías de bolsa, ocasionan enormes gastos económicos y de tiempo en las campañas de muestreo, además de imprecisiones estadísticas que no las hacen representativas. En este trabajo se emplean una serie de criterios que dan basamento para la recomendación de una nueva red de estaciones a partir de estudios previos de metales pesados, hidrocarburos, pesticidas y del bentos, los cuales permiten elaborar una red de monitoreo óptima. Se tuvieron en cuenta criterios diferentes y pruebas estadísticas de análisis multivariado. La red propuesta para estudios de indicadores biológicos del bentos y contaminantes en sedimentos queda...

Interacciones entre corales y macroalgas: dependencia de las especies involucradas
Provedor de dados: 20
Autores: Márquez, J.C.; Díaz, J.M.
Macroalgae proliferation on coral reefs has been a recognized phenomenon for the past two decades and is generally entitled to the human activities on the coasts. Even thought, the role of competition in this process is not clear and it has been assumed that algae are competitively superior to corals, even when it has been demonstrated that this is not always the case. It is probable that the result of coral-macroalgae depends upon the species involved. The goal of this study was to demonstrate that there is a dependence relation between interaction category and interacting species. In order to resolve this, quantifications of interactions per category along 20 m transects were done on three representative localities at the Archipielago de San Bernardo....

Benthic communities and geomorphology of the Tesoro Island Coral Reef, Colombian Caribbean
Provedor de dados: 20
Autores: Sánchez-M., Juan M.
The benthic communities distribution in Tesoro Island (Colombian Caribbean) coral reef was determinad by cartography of reef morphology and functional groups from aerial photographs, theodolite triangulation, and bottom transects over depths ranging from O to 30 m. Tesoro Island is a sand cay reef developed over an emerged reef platform whose basal cone possibly originated by mud diapirism on the continental shelf. The benthic communities are distributed as subzones of the geomorphologic units. The reef crest lies along the breaker zone, formed by Millepora spp. buttresses covered on their tops by Palythoa spp. and seawardly by a turf of Dictyota spp. The rear reef (varying from 0.5-1.5 m ¡n depth) is composed of pavement and grooves with live Porites...

Zygochlamys patagonica (King and Broderip, 1832) is an ecosystem engineer mollusk which forms aggregations or banks, of different densities, in the main frontal systems of the SW Atlantic Ocean. The objectives of this work were to analyze the composition, biomass, diversity and species richness of the benthic invertebrate assemblages at different scallop densities as well as the variability of their trophic webs at high and low scallop densities. For this, samples of the benthic invertebrate assemblages were taken at the Shelf Break Front with a non-selective epibenthic dredge. It was evaluated if the abundance (ind/m2) or biomass (colonial species, gr/m2) of the different taxa varied with scallop densities. The results showed that from 14 analyzed, the...

Diatomeas antárticas: vida en las sombras y en el frío
Provedor de dados: 20
Autores: Uribe, P.
En la Antártica se ha descrito un grupo de microalgas (diatomeas bentónicas), que viven en el fondo, pegadas a las piedras o sedimentos, capaces de hacer  fotosíntesis con niveles de luz muy bajos e incluso cubiertas por una capa de hielo marino. El proyecto “Identificación de biomarcadores de fluctuaciones de la cobertura de hielo en diatomeas bentónicas de la Península Antártica” busca conocer las características fisiológicas que determinan la adaptación de estas microalgas al medio polar, características que luego sirvan como marcadores biológicos (o biomarcadores) de esta capacidad de vivir en las zonas más oscuras. Paulina Uribe describe este proyecto y establece un curioso vínculo con las ideas y circunstancias de Darwin.

The faunistic composition of invertebrate by-catch associated with the Patagonian scallop Zygochlamys patagonica fishery before its development were studied. Analyzed material was sampled from catches performed in different beds with the F/V Erin Bruce during 1995, all of them in undisturbed areas, in the Argentine continental shelf. Macrofaunal species were identified, weighted and percentages of presence estimated. By-catch invertebrate species were determined for every bed, mainly invertebrates without present commercial value. This baseline information is considered a useful tool to detect structural changes in the benthic communities in relation to the conservation of possible substrates of recruitment of this resource and to estimate the evolution of...

Cet article présente les résultats d'une étude comparative de trois séries de prélèvements dans la zone proche du canal de Bassam avant, 6 mois et 20 mois après son ouverture en septembre 1987. Les effets constatés sont la diminution de l'abondance et la modification de la composition de la macrofaune benthique. Ces effets semblent de longue durée, sans reprise en ce qui concerne l'espèce la plus abondante, Corbula trigona. Les changements observés dans la structure des peuplements sont dus essentiellement à l'augmentation de la salinité, et à un degré moindre, aux modifications de la nature du sédiment.

Specific diversity of the benthic macrofauna within the western coast of Tunis bay and the Djerba island coast (southwestern Mediterranean)
Provedor de dados: 20
Autores: Afli, A.; Ibin Chaabane, K.; Chakroun, R.; Jabeur, Ch.; Ramos-Espla, A.A.
In this study, 21 stations were sampled, 11 in the Djerba island coast and 10 in the western coast of Tunis bay. Then, samples were sifted on a square mesh of 1 mm a side, and the animals collected were identified and counted. Lacking an efficient single index suitable for application in all situations, several traditional nonparametric indices of biodiversity were selected, calculated and discussed. Results show that the community composition is totally different in the two studied sites, and, within each site, several species are common, butthey exchange the leader ranks from one station to another. For biodiversity measurement and since results show varying values depending on indices at several stations, an arithmetic mean index was calculated at each...

La costa patagónica y en especial el golfo San Jorge (Mar Argentino, Atlántico sudoccidental), son zonas de gran interés pesquero, destacándose este último por poseer una de las especies de mayor valor comercial del Mar Argentino: el langostino patagónico Pleoticus muelleri. En un nuevo concepto de análisis integrado, se estudia la relación de los recursos con su ambiente. En el caso particular del langostino, dado su hábito bentónico, resulta de importancia acceder al conocimiento sobre las distintas especies que conforman las comunidades bentónicas y sus interrelaciones. El estudio de las comunidades bentónicas del Golfo San Jorge ha sido realizado por Roux et al. (1995, 1997) consistiendo principalmente en la confección de un amplio inventario...

Size spectra, body width and morphotypes of intertidal nematodes: an ecological interpretation
Provedor de dados: 27
Autores: Tita, G.; Vincx, M.; Desrosiers, G.
Nematode species from three intertidal assemblages (St Lawrence Estuary, Quebec, Canada) were studied in order to form an ecological interpretation of three allometric attributes: body width, size spectra, and morphotypes. The three assemblages were characterized by a very similar sediment grain median (Md) but different silt-clay proportions: A1 (upper-tidal level; Md=122 µm; silt=34.8%), A3 (mid-tidal level; Md=182 µm; silt=12.8%), and A5 (lower-tidal level; Md=122 µm; silt=6.8%). Silt-clay proportions were an influential factor in determining the mean nematode body width, used as a morphological discriminant between burrowing and interstitial organisms. A plot of the number of species vs the body width-classes showed two peaks: between 19.3 and 22.6 µm...

The hyperbenthos
Provedor de dados: 27
Autores: Mees, J.; Jones, M.B.
The hyperbenthos is a term applied to the association of small animals living in the water layer close to the sea bed. The species composition of the hyperbenthos is distinctly different from that of other benthic and planktonic groupings, and includes endemic species, planktonic species derived from their downward extensions (often with seasonal periodicity) and endo- or epibenthic species as they emerge into the water column (usually in diel cycles). In nearly all marine ecosystems investigated to date, there is a general increase in the biomass at the benthic boundary layer (hyperbenthon) relative to the water column immediately above it, yet the zone and its fauna remain relatively poorly studied. Sampling these often highly mobile animals is not easy...

Habitat verlies en degradatie is één van de belangrijke ecologische problemen van deze eeuw. Hoewel alle ecosystemen hieronder te lijden hebben, blijken wetlands of waterrijke gebieden, op wereldschaal vrij zeldzame gebieden, onder zeer zware antropogene druk te staan. Het is daarom ook niet te verwonderen dat deze ecosystemen sinds meerdere jaren een belangrijke prioriteit vormen voor het natuurbehoud. Binnen de wetlands vormen estuaria zeer produktieve systemen waarvan het rijke voedselaanbod wordt benut door grote aantallen steltlopers, die buiten het broedseizoen bijna volledig op dergelijke getijdengebieden zijn aangewezen. Het belang van het Deltagebied (NI.) en met name de getijdengebieden van Ooster- en Westerschelde voor watervogels worden kort...

A seasonally varying biotope at Signy Island, Antarctic: implications for meiofaunal structure
Provedor de dados: 27
Autores: Vanhove, S.; Beghyn, M.; Van Gansbeke, D.; Bullough, L.W.; Vincx, M.
Under the typical high-latitude conditions of temperature, productivity and settlement of chlorophyll and phaeophytin to the sediment, many benthic organisms in the Antarctic show strong seasonal variation. Although meiofauna comprise an important component of the southpolar benthic ecosystem, our knowledge of them is limited. The metazoan meiofauna and the surrounding sediments were studied fortnightly for 18 mo in a shallow bay at Signy Island (Factory Cove, South Orkneys, Antarctica) to test whether and how the temporal variability of the environment influenced meiobenthos dynamics. By examination of the distribution of the abundance and biomass of the total community, the density of higher taxonomic groups, and of individual dominant nematode genera...

TOWARDS A REVIEW OF THE DECAPOD CRUSTACEA FROM THE REMOTE OCEANIC ARCHIPELAGO OF TRINDADE AND MARTIN VAZ, SOUTH ATLANTIC OCEAN: NEW RECORDS AND NOTES ON ECOLOGY AND ZOOGEOGRAPHY
Provedor de dados: 84
Autores: TAVARES,MARCOS; CARVALHO,LEINA; MENDONÇA JR.,JOEL BRAGA DE.
ABSTRACT The remoteness of the Trindade and Martin Vaz young volcanic archipelago (TMV) raises questions about the source of its marine benthic fauna and levels of endemism. Addressing these questions requires a comprehensive knowledge of the taxonomic composition of the marine fauna of the islands. A five-year survey in the shallow marine waters (up to 30 m) and a literature review on the data published for TMV have been conducted to document the biodiversity of the benthic fauna. Here we report on ten new records of decapod crustaceans from TMV: Gnathophyllum americanum and Thor amboinensis are circumtropical in distribution, whereas Stenopus hispidus, Gnathophylloides mineri and Parribacus antarcticus are disjunct circumtropical species as their...

Short-term stability of estuarine benthic assemblages: are storms pattern-defining events?
Provedor de dados: 103
Autores: Negrello Filho,Orlei A.; Lana,Paulo C.
Storms, associated with strong winds and heavy rains, are often the most severe physical disturbances in shallow coastal areas causing instability to sedimentary environments. We hypothesized herein that if storms influence short-term assemblage structure of macrofauna, then assemblages should change after storms, while remaining relatively stable over calm weather conditions. The study was conducted at the subtropical Paranaguá Bay, in southern Brazil. We selected four 700 m² sites, at the estuarine outlet, to monitor changes in number of species, number of individuals and Shannon diversity. Sampling was arranged considering the weather forecast so that both before and after conditions could be recorded. Data of each site was tested separately to access...

Species composition and abundance of the benthic community of Axiidea and Gebiidea (Crustacea: Decapoda) in the Marapanim Bay, Amazon estuary, northern Brazil
Provedor de dados: 103
Autores: Silva,Dalila Costa; Martinelli-Lemos,Jussara Moretto.
The thalassinideans (Axiidea and Gebiidea) encompasses approximately 615 species with reclusive habits, generally confined to extensive galleries burrowed into the sand or mud and, more rarely, in openings in reefs or the cavities of sessile animals such as sponges and coral. These species use the galleries for shelter, feeding and breeding, except during the pelagic larval stage. They inhabit estuaries, bays, lagoons, beaches, seas and both tropical and temperate oceanic areas throughout the world, distributed predominantly in the intertidal zone (mid-littoral and infralittoral zones). The aim of the present study was to assess the species composition and abundance of thalassinideans, comparing two micro-habitats (consolidated and non-consolidated...

A comprehensive literature review was conducted to determine the species richness of all the possible taxa of free-living benthic marine invertebrates in Chile. In addition, the extent of endemism to the Pacific Islands and deep-sea, the number of non-indigenous species, and the contribution that the Chilean benthic marine invertebrate fauna makes to the world benthic marine invertebrate fauna was examined. A total of 4,553 species were found. The most speciose taxa were the Crustacea, Mollusca and Polychaeta. Species richness data was not available for a number of taxa, despite evidence that these taxa are present in the Chilean benthos. The Chilean marine invertebrate benthic fauna constitutes 2.47 % of the world marine invertebrate benthic fauna. There...

The distribution, population dynamics and secondary production of the polychaete Euzonus furciferus was studied in Atami Beach (Southern Brazil), from February 1992 to March 1993. Euzonus furciferus Ehlers, 1897 is the only deposit feeder species of the upper intertidal region. The organisms were present in the sandy beach all over the year, concentrated in a narrow band, and reaching maximal densities of 3,029 individuals m-2. Peaks of abundance occurred in September 1992, with a mean of 681.8 individuals m-2. Recruitment occurred in winter, with a peak in July. Mean annual biomass was estimated in 0.218 gAFDW m-2, with a total annual production of 0.466 gAFDW m-2 y-1, giving a P/B ratio of 2.13 y-1. Similar values were found for a filter-feeder...

Autores: MARIA,TATIANA F.; VANAVERBEKE,JAN; VANREUSEL,ANN; ESTEVES,ANDRÉ M.
ABSTRACT In this review, we summarize existing knowledge of the ecology of sandy-beach nematodes, in relation to spatial distribution, food webs, pollution and climate change. We attempt to discuss spatial scale patterns (macro-, meso- and microscale) according to their degree of importance in structuring sandy-beach nematode assemblages. This review will provide a substantial background on current knowledge of sandy-beach nematodes, and can be used as a starting point to delineate further investigations in this field. Over decades, sandy beaches have been the scene of studies focusing on community and population ecology, both related to morphodynamic models. The combination of physical factors (e.g. grain size, tidal exposure) and biological interactions...

Autores: Beghelli,Frederico Guilherme de Souza; Santos,André Cordeiro Alves dos; Urso-Guimarães,Maria Virgínia; Calijuri,Maria do Carmo.
The purpose of this work was to verify the benthic macroinvertebrates community responses through environmental factors along a headwater tropical reservoir. Samplings were taken with a Van-Veen grab along the reservoir in littoral and profundal regions and in the headwater, next to the dam and the middle of the reservoir. Samples were taken during both wet and dry seasons. Dissolved oxygen concentrations, electric conductivity, temperature and pH near the sediment have been performed in situ, at every sampling station by using a multiprobe and Secchi disc. Total water phosphorus and chlorophyll a concentrations were analyzed to determine the trophic state index. Sediment's organic matter, total phosphorus, nitrogen concentrations and granulometric...

Autores: González-Solis,Alicia; Torruco,Daniel; Torruco-González,Ángel D.
ABSTRACT The phylum Mollusca is widely distributed in all types of environments. The species it contains are important for their multiple uses as food (as part of several trophic chains), as vectors of other groups of organisms, for the extraction of substances, and as sentinels of natural and induced environmental changes. In this work, a comparative evaluation of the malacological biodiversity associated with different habitats in the Los Petenes Biosphere Reserve in Campeche and in eight coastal water bodies in southeastern Mexico was performed. To obtain data comparable to those that were used in a previous study, data from the Los Petenes mollusks were obtained by collection of sediment cores 10 cm in diameter at a depth of 15 cm at 20 sites in...

A new mini box corer for sampling muddy bottoms in antarctic shallow waters
Provedor de dados: 52
Autores: Echeverría,Carlos Alejandro; Lavrado,Helena Passeri; Campos,Lúcia; Paiva,Paulo Cesar de.
A new Mini Box Corer (MBC-GEAMB) was developed for bottom sampling in Antarctic shallow waters down to 100 m depth from a small vessel. It consists of a detachable stainless steel box with a total sampling area of 0.0625 m², and a closing arm with a detachable blade without an external frame. MBC allowed stratified bottom sampling and good quality samples comparable to those obtained through diving. A comparison between the MBC-GEAMB and a 0.056 m²van Veen grab (VV) was undertaken for the benthic macrofaunal composition in Admiralty Bay, King George Island (Antarctica). MBC and VV samples were taken from three depths (20, 30 and 60m) in two sites. Total densities sampled with the MBC were up to 10 times higher than those obtained with van Veen grab. VV...

This study aimed to predict the biological parameters (species composition, abundance, richness, diversity and evenness) of benthic assemblages in southern Brazil estuaries using models based on environmental data (sediment characteristics, salinity, air and water temperature and depth). Samples were collected seasonally from five estuaries between the winter of 1996 and the summer of 1998. At each estuary, samples were taken in unpolluted areas with similar characteristics related to presence or absence of vegetation, depth and distance from the mouth. In order to obtain predictive models, two methods were used, the first one based on Multiple Discriminant Analysis (MDA), and the second based on Multiple Linear Regression (MLR). Models using MDA had...
